Subjective appraisal of orthodontic practices. An investigation into perceived practice characteristics associated with patient and parent treatment satisfaction.

Based on a comprehensive in-practice questionnaire survey among 254 school-age patients and their parents, the subjective perception and evaluation of orthodontic care was investigated. By means of refined statistical analysis, three types of practice showing significantly distinct image profiles were identified. Likewise, the set of discriminating variables was reduced and assigned to the fundamental concepts of 'interpersonal satisfaction' and 'perceived efficacy' which appeared to play a crucial part in the crystallization of both patients' and parents' contentedness with the treatment received. To take account of the interdependence of instrumental and social factors, a model of perceived practice similarity is suggested; its significance regarding treatment decisions and future research efforts is pointed out.
